[Industrial applications]

 The present invention relates to a stopper mechanism that restricts the opening movement of a lid to a predetermined fully open position in a lid opening / closing device that can open and close the lid of a console box of an automobile from both sides (driver side and passenger side).

[0002]

[Prior art]

 In a console box or the like of an automobile, a lid may be opened and closed from both sides (a driver's seat side and a passenger's seat side) as seen in, for example, JP-A-3-7636. Conventionally, in this type of double lid opening / closing device, a stopper mechanism for the lid is not particularly provided, and the lid can usually be opened until its edge or the like comes into contact with the opening edge of the box or the like. It was

As disclosed in Japanese Utility Model Laid-Open No. 60-42869, the lid is supported by a pair of left and right arcuate stays with respect to the box so that the lid can be opened freely, and the lid is provided at the end of the arcuate stay. There has also been proposed a device for preventing the opening movement of the lid to a predetermined fully opened position by bringing the collar-shaped portion into contact with the inner surface of the box. However, with this device, when the lid is opened, the stay greatly extends to the side surface, and when the lid is closed, the stay hangs down into the box for a long time.

[0004]

[Problems to be solved by the device]

 Therefore, in the opening / closing device as disclosed in the above-mentioned Japanese Patent Laid-Open No. 3-7636, the edge of the lid or the like is pressed against the opening edge of the box each time the lid is opened widely, so that this contact Damage such as peeling off of the surface finishing layer in some parts may occur. Further, with the device disclosed in Japanese Utility Model Laid-Open No. 60-42869, there is a problem that the stay becomes an obstacle when the lid is opened and the appearance is damaged, and the stay rattles when the lid is closed. However, there was a problem such as abnormal noise.

The present invention has been made by paying attention to the problems of the conventional techniques, and has a structure that does not disturb the rattling and causes less rattling, so that the lid can be opened up to a predetermined fully open position. It is an object of the present invention to provide a stopper mechanism for a lid opening / closing device that can prevent the above.

[0006]

[Means for Solving the Problems]

 The gist of the present invention for achieving such an object is a stopper mechanism of a lid opening / closing device capable of opening and closing the lid body (2) from both left and right sides, one end of which is a front-back direction of the lid body (2). An extendable telescopic rod (40) that is swingably attached to the center of the end face and a longitudinal inner end face of the opening to which the lid (2) is attached are provided so as to extend in the left-right direction, and the other end of the telescopic rod (40). And a guide means (50) for supporting and guiding the swingable and slidable in the left and right directions, and when the lid body (2) is opened to the fully opened position, the telescopic rod (40) extends to the limit length. In addition, the other end of the telescopic rod (40) is positioned at the sliding limit of the guide means (50) to prevent the lid (2) from further opening, and the limit length of the telescopic rod (40) and Of the sliding limit of the guide means (50) The stopper mechanism of the lid opening / closing device is characterized in that the position is set.

[0007]

[Action]

 According to the stopper mechanism of the lid opening / closing device of the present invention, when the lid body (2) is opened to the fully open position, the telescopic rod (40) extends to the limit and the sliding end thereof slides on the guide means (50). Since it is located at the limit of movement, the telescopic rod (40) is stretched between the opening to which the lid is attached and the lid (2) to prevent further opening of the lid (2).

[0008] The telescopic rod that constitutes the stopper mechanism has its both ends supported at all times, and thus is difficult to rattle. Further, when the lid body (2) is opened, the telescopic rod (40) is in a standing posture along the lid body (2), so that it does not get in the way and does not impair the appearance.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 are side views in which a part of a console box to which the lid opening / closing device of this embodiment is applied is broken at an end where a stopper mechanism is provided, and FIG. 3 is a vertical cross-sectional view of the console box. Is a partial cross-sectional view of the telescopic rod that constitutes the stopper mechanism of this embodiment, FIGS. 5 and 6 are top views of the console box, and FIG. 7 is a side view in which a portion of the console box is cut away at the center.

The console box is made of, for example, a synthetic resin, and includes a box body 1 having a rectangular parallelepiped shape and a lid body 2 that closes an upper opening of the box body 1. The lid 2 is openable in both left and right directions around the hinge pins 11a and 11b or the hinge pins 12a and 12b.

As shown in FIG. 1, the stopper mechanism of the lid opening / closing device of the present embodiment has one end swingably attached to the center of the end face of the lid body 2 in the front-back direction (vertical direction in FIG. 5). The telescopic rod 40 and the edge 1a located in front of and behind the upper opening of the box body 1 are formed so as to extend in the left-right direction (the left-right direction in FIG. 5), and the other end of the telescopic rod 40 is swingable. The slit 50 (guide means) is slidably supported in the left-right direction. The stopper mechanism may be provided on both front and rear sides of the lid body 2, or may be provided on only one side.

The telescopic rod 40 has a tubular portion 41 and a rod-shaped portion 42 having a rectangular cross section which are housed in a recess 5 formed in the end surface of the lid 2 when the lid 2 is closed. The one end side expands and contracts by being slidably fitted in the tubular portion 41 and protruding and retracting. A compression coil spring 43 is compressed and inserted into the tubular portion 41 to urge the rod-shaped portion 42 in the projecting direction (that is, the extending direction), but the rod-shaped portion 42 is inserted as shown in FIG. By engaging the large-diameter portion formed at the end portion with the base end of the tubular portion 41, the protruding length (that is, the extension length) of the rod-shaped portion 42 is regulated.

As shown in FIG. 3, a pin-shaped portion 44 penetrating a round hole of a wall forming the recess 5 of the lid body 2 is provided at an end (one end) of the telescopic rod 40 on the cylindrical portion 41 side. The end portion of the telescopic rod 40 on the side of the tubular portion 41 is swingable with respect to the lid body 2 via the pin-shaped portion 44. Further, as shown in FIG. 3, a pin-shaped portion 45 penetrating the slit 50 is provided at the end portion (the other end) on the rod-shaped portion 42 side of the telescopic rod 40, and the pin-shaped portion 45 is used for expansion and contraction. An end of the rod 40 on the side of the rod-shaped portion 42 is swingably and slidably supported by the slit 50.

The limit length of the telescopic rod 40 and the positions of both ends of the slit 50 (the position of the sliding limit of the pin-shaped portion 45) are opened to a position where the lid body 2 is upright as shown in FIG. 1 (fully open position). At this time, the telescopic rod 40 extends to the limit length and the pin-shaped portions 45 are positioned at both ends of the slit 50 so as to prevent further opening of the lid body 2. In addition, the friction coefficient between the pin-shaped portion 45 and the slit 50, the biasing force of the compression coil spring 43, or the like causes the slip between the pin-shaped portion 45 and the slit 50 when the lid 2 is closed from the fully open position. It is set so that (sliding) does not occur.

Next, the operation of the stopper mechanism will be described. When the lid 2 is opened to the right as shown by the chain line in FIG. 1 from the state where the sliding end (pin-shaped portion 45) of the telescopic rod 40 is at the left end of the slit 50, the telescopic rod 40 rotates counterclockwise. While oscillating, the urging force of the compression coil spring 43 extends to push up the lid body 2 to assist the operation of opening the lid body 2, and as the lid body 2 further opens, the sliding end portion of the expansion rod 40 moves. While sliding the slit 50 to the right, it further swings so as to rise up as a whole. Then, when the lid 2 is opened to the fully open position, the telescopic rod 40 extends to the limit and its sliding end is located at the right end of the slit 50, so that the extension rod 40 moves the lid 2 and the box body 1 together. It is stretched between and to prevent further opening of the lid 2.

Even if the lid body 2 is left in the fully opened position, no slippage occurs between the pin-shaped portion 45 and the slit 50 as described above, so the lid body 2 is held at the fully opened position. Further, when the lid body 2 is pushed inward from this fully opened position to be closed, the telescopic rod 40 swings counterclockwise while the sliding end portion of the telescopic rod 40 remains at the right end of the slit 50. When retracted, it is stored in the posture opposite to the state shown in Fig. 1.

Next, when the lid 2 is opened to the left as shown by the chain line in FIG. 2 from the state where the sliding end (pin-shaped portion 45) of the telescopic rod 40 is at the left end of the slit 50, the telescopic rod 40 40 also swings counterclockwise, and in this case also extends by the biasing force of the compression coil spring 43 so as to push up the lid body 2 to assist the operation of opening the lid body 2 and rise up as a whole. Then, when the lid body 2 is opened to the fully open position, the telescopic rod 40 also extends to the limit and the sliding end portion thereof is located at the left end of the slit 50 in this case as well, so that the telescopic rod 40 serves as the lid body 2 and the box body. 1 to prevent the lid 2 from further opening.

Even if the lid 2 is left in the fully opened position, the lid 2 is still held in the fully opened position because no slip occurs between the pin-shaped portion 45 and the slit 50 as described above. Further, when the lid body 2 is pushed inward from this fully open position to be closed, the telescopic rod 40 swings clockwise while the sliding end of the telescopic rod 40 remains at the left end of the slit 50. While shrinking, it returns to the original state shown in FIG.

In this way, with the stopper mechanism, the telescopic rod 40 rises along the lid body 2 in the fully open position (in this case, the upright posture) regardless of which side the lid body 2 is opened. Further opening movement is prevented and the posture of the lid body 2 is maintained. Therefore, the end portion of the lid body 2 is prevented from hitting the box body 1 and damaged, and there is no obstacle to keep the box body 1 fully opened even if the lid body 2 is released. It is easy to put things in and take them out, and the appearance is also improved. Moreover, since the telescopic rod 40 constituting the stopper mechanism is always supported at its both ends, it is difficult to rattle, and abnormal noise is unlikely to occur even when there is vibration during traveling of the vehicle or the like.

The stopper mechanism of the present invention is not limited by the configuration of the lid opening / closing device body (the configuration that allows the lids to open both sides), but in this embodiment, the configuration of the lid opening / closing device body is as follows. It looks like.

That is, as shown in FIGS. 5 to 7, left hinge pins 11a and 11b are provided at left and right ends of both end faces in the front-rear direction of the lid body 2 so that the left and right ends can be retracted with their axes aligned with each other. The right and left hinge pins 12a and 12b that are provided so as to be retractable with their axes aligned, the compression coil vanes 13a, 13b, 14a, and 14b (biasing members) that bias these hinge pins in the protruding direction, and each of the hinge pins. A pulling cable 17a for connecting the left operation button 15 or the right operation button 16 slidably provided to the pair and the two hinge pins corresponding to these operation buttons 15 and 16 respectively. , 17b, 18a, 18b and the operation buttons 15, 16 pushed to the mating disengagement position, which will be described later, respectively, and slide in the return direction. It comprises a left engagement member 19 or a right engagement member 20 for blocking the above, and a rod 21 slidably arranged between the two operation buttons 15 and 16 for preventing simultaneous operation.

The left hinge pin 11a, 11b or the right hinge pin 12a, 12b is rotated in a bearing hole (not shown) formed on both inner surfaces of the edge portion 1a positioned before and after the upper opening of the box body 1 in the protruding state. They fit freely and are arranged on the same axis.

The left operation button 15 or the right operation button 16 is located at one of the left and right ends of the lid body 2 where the corresponding hinge pin is provided (in this case, the left operation button 15 is at the left end). The right operation button 16 is arranged at the right end) and the sliding direction is the left-right direction along the upper surface of the lid. That is, on the lower surface sides of the left and right ends of the lid body 2, there are formed concave portions 3 and 4 having a square cross section, which are located at the same position in the front-back direction of the lid body 2 and extend inward along the upper surface of the lid body 2. The operation buttons 15 and 16 are slidably fitted in the recesses 3 and 4, respectively.

Sliding shafts 22 and 23 extending through the inner walls of the recesses 3 and 4 are formed at both ends of the inner end surface of the left operation button 15 or the right operation button 16, respectively. The large-diameter portions at the tips of the moving shafts 22 and 23 are configured so that the operation buttons 15 and 16 do not protrude from the left and right end surfaces of the lid body 2 by contacting the inner walls of the recesses 3 and 4. Stoppers 24 and 25 for restricting outward sliding strokes of 15 and 16 are configured.

Then, compression coil springs 26 and 27 are attached around the sliding shafts 22 and 23 and between the operation buttons 15 and 16 and the walls on the far side of the recesses 3 and 4, respectively. , 16 are urged outward. Further, projections 28a, 28b, 29a, 29b extending through the side walls of the recesses 3, 4 are formed on both side surfaces of the left operation button 15 or the right operation button 16, respectively, and the pull cables 17a, One end of 17b, 18a, 18b is fixed. On the side walls of the recesses 3 and 4, elongated holes (not shown) are formed in the sliding direction of the operation buttons 15 and 16 at the portions where the protrusions 28a, 28b, 29a and 29b penetrate, and the interference is prevented. I'm trying not to get up.

Further, the sliding stroke of the operation buttons 15 and 16 is set to a value equal to or larger than the stroke for each hinge pin to completely come out of the bearing hole and sink into the lid body 2. The positions of the operation buttons 15 and 16 when completely removed from the bearing hole and submerged in the lid body 2 are the fitting release positions. Further, recesses 15a and 16a, in which the left side engaging member 19 or the right side engaging member 20 is disposed, are formed on the lower surface side of the operating buttons 15 and 16, respectively, and inside these recesses 15a and 16a, the left side is formed. Steps 15b and 16b with which the engaging member 19 or the right engaging member 20 engages are formed.

The pulling cables 17 a, 17 b, 18 a, 18 b are provided with lids so that the operation buttons 15, 16 for releasing the fitting of the corresponding hinge pins are pushed in the lid 2. The bodies 15 and 16 are attached to the protrusions 28a, 28b, 29a and 29b of the operation buttons 15 and 16 by being drawn around from the left and right ends.

That is, at the left and right ends of the lid body 2, on both sides of the recesses 3 and 4, respectively, the end portions of the lid body 2 are positioned closer to the end portions of the lid body 2 than the protrusions 28a, 28b, 29a, 29b. The sliding cables 17a, 17b, 18a, 18b are respectively provided with sliding contact pins 30a, 30b, 31a, 31b, and the pulling cables 17a, 17b, 18a, 18b are respectively connected to the sliding contact pins 30a, 30b, 31a, 31b. It is wound around and drawn around, and is attached to the protrusions 28a, 28b, 29a, 29b from the end side of the lid body 2.

The lengths of the pull cables 17a, 17b, 18a, 18b are such that the left hinge pin 11a, 11b or the right hinge pin 12a, 12b fits in the bearing hole, and the left operation button 15 or the right operation button 16 is In the free state (the stoppers 24 and 25 are effective and the end surface of the left operation button 15 or the right operation button 16 is aligned with the position of the end surface of the lid body 2), as shown in FIG. , Each pulling cable is set to a value at which it can be tensioned without sagging.

The left side engaging member 19 or the right side engaging member 20 has a shape in which a tensile cable such as a steel wire is bent into an elongated loop shape, and both ends of the tensile cable are extended in parallel in the lateral direction. Each of the ends is inserted into and supported by the two lateral holes of the protrusions 32 and 33 formed on the bottom surfaces of the recesses 3 and 4, and is oscillated in the vertical direction with the deformation of the whole.

The left side engaging member 19 or the right side engaging member 20 has one end outside the loop-shaped portion bent downward toward the open end surface 1b of the box body 1 as shown in FIG. In the natural state (non-deformed state), the mounting position and the like on the protrusions 32 and 33 are set so that one end of the lid 2 extends downward from the lower surface of the lid 2 and the other end of the inner side faces upward. As a result, when the left side operation button 15 or the right side operation button 16 is pushed to a position where the hinge pin is disengaged (hereinafter referred to as a disengagement position), the left side engagement member 19 or the right side engagement member is automatically operated. The other end of 20 is adapted to engage with the steps 15b and 16b.

The rod 21 is arranged such that both ends thereof penetrate through the inner walls of the recesses 3 and 4, respectively, and is made slidable in the same direction as the operation buttons 15 and 16, so that the operation buttons 15 and 16 can be slid. When one of the operation buttons 15 and 16 slides to the fitting release position, both ends substantially contact the inner end surfaces of the two operation buttons 15 and 16. A compression spring 35 is provided between one end of the rod 21 and the wall forming the inner surface of the recess 4 to prevent the rattling of the rod 21.

Next, the operation of the lid opening / closing device body will be described. First, when the lid body 2 is attached to the upper opening of the box body 1 and the left hinge pins 11a and 11b and the right hinge pins 12a and 12b are respectively fitted in the bearing holes of the opening edge portion 1a, these hinge pins are fitted. Unless the left operation button 15 or the right operation button 16 is pushed by the force of the springs 13a, 13b, 14a, 14b that urge the springs 13a, 13b, 14a, 14b, the state in which the lid 2 closes the opening is maintained. (At this time, the left side engaging member 19 or the right side engaging member 20 is pushed into the lid body 2 with its outer end contacting the upper opening end face 1b of the box body 1, and its inner end is When the lid 2 is to be opened from the right side, for example, when the lid 2 is to be opened from the right side, it is in the deformed state. You can open it with one touch by placing your hand near the right operation button 16 at the right end of 2 and pressing the right operation button 16 with your finger to pull it. That is, as shown in FIG. 6, when the right operation button 16 is pushed to the disengagement position, only the right hinge pins 12a and 12b are pulled through the pull cables 18a and 18b and pulled into the lid body 2, respectively. Since it is inserted, the lid body 2 can be opened from the right side by using the left hinge pins 11a and 11b as swing axes.

On the other hand, if a hand is placed near the left side operation button 15 at the left end of the lid body 2 and the right side operation button 16 is pushed and pulled to the disengagement position with the fingers of this hand, the left hinge pin 11a, Since only 11b is pulled through the pull cables 17a and 17b and drawn into the lid body 2 respectively, the lid body 2 can be opened from the left side with one touch by using the right hinge pins 12a and 12b as swing axes.

At this time, for example, when the left operation button 15 is pushed to the disengagement position in order to open the lid body 2 from the left side, as shown in FIG. 7, the left side engagement member 19 is restored from its deformed state. The force automatically swings counterclockwise, and the inner end of the left side engaging member 19 automatically engages with the step portion of the left side operating button 15 to prevent the left side operating button 15 from returning. The rod 21 is interposed between the two operation buttons 15 and 16 to prevent the right operation button 16 from sliding even if an external force in the pushing direction is applied to the right operation button 16. Therefore, once the lid 2 is opened to either side, the hinge pin on the opened side once pulled in or the remaining hinge pin supporting the lid 2 is pulled in and the lid 2 comes off. There is no end.

Then, in order to close the lid body 2 to the original state, it suffices to simply tilt the opened lid body 2 until it abuts on the upper opening end surface 1b of the box body 1. Then, the outer end of the opening-side engaging member is pushed by the opening end surface 1b and swings, and the inner end of the engaging member is disengaged from the stepped portion of the operation button, so that the lid described above is released. The body 2 returns to the state in which the opening is closed.

That is, for example, when the lid body 2 opened from the left side is closed, as shown in FIG. 7, the left side engaging member 19 is pushed at the outer end portion thereof to the opening end surface 1b of the box body 1 and the timepiece is closed. It swings around and the engagement between the outer end of the left side engaging member 19 and the step 15b is released. Therefore, the left operation button 15 or the left hinge pin 11a, 11b returns to its original position by the restoring force of the spring 13a, 13b or the spring 26, and the left hinge pin 11a, 11b fits into the bearing hole on the inner surface of the edge 1a. .

[Effect of device]

 According to the stopper mechanism of the lid opening / closing device of the present invention, even if the lid is opened on either side, the telescopic rod rises along the lid and prevents further opening of the lid at a predetermined fully open position. This prevents the edge of the lid from hitting the edge of the opening where the lid is attached and damaging it, and there is nothing that overhangs and obstructs the product, making it easy to take things in and out of the opening. Also improves. Moreover, since the telescopic rod that constitutes the stopper mechanism is always supported at its both ends, it is difficult to rattle, and abnormal noise is unlikely to occur even when there is vibration during traveling of the vehicle or the like.
